This Ayah means that those who assume the Ihram for Hajj or `Umrah are required to avoid the Rafath, meaning, sexual intercourse. Allah's statement here is similar to His statement:

﴿أُحِلَّ لَكُمْ لَيْلَةَ الصِّيَامِ الرَّفَثُ إِلَى نِسَآئِكُمْ﴾

(It is made lawful for you to have Rafath (sexual relations) with your wives on the night of the fast.) (2:187)

Whatever might lead to sexual intercourse, such as embracing, kissing and talking to women about similar subjects, is not allowed. Ibn Jarir reported that Nafi` narrated that `Abdullah bin `Umar said, "Rafath means sexual intercourse or mentioning this subject with the tongue, by either men or women.'' `Ata' bin Abu Rabah said that Rafath means sexual intercourse and foul speech. This is also the opinion of `Amr bin Dinar. `Ata' also said that they used to even prevent talking (or hinting) about this subject. Tawus said that Rafath includes one's saying, "When I end the Ihram I will have sex with you.'' This is also the same explanation offered by Abu Al-`Aliyah regarding Rafath. `Ali bin Abu Talhah said that Ibn `Abbas said, "Rafath means having sex with the wife, kissing, fondling and saying foul words to her, and similar acts.'' Ibn `Abbas and Ibn `Umar said that Rafath means to have sex with women. This is also the opinion of Sa`id bin Jubayr, `Ikrimah, Mujahid, Ibrahim An-Nakha`i, Abu Al-`Aliyah who narrated it from `Ata' and Makhul, `Ata Al-Khurasani, `Ata' bin Yasar, `Atiyah, Ibrahim, Ar-Rabi`, Az-Zuhri, As-Suddi, Malik bin Anas, Muqatil bin Hayyan, `Abdul-Karim bin Malik, Al-Hasan, Qatadah and Ad-Dahhak, and others.
